Our present invention aims to finish the wrapping of boxes by blanksthat have been partially wrapped in another blank and box wrappingmachine, with a view of increasing the production of completed boxes andalso of producing wrapped boxes that are more tightly wrapped and thatare wrapped with a more artistic finishing pressure than most boxeswrapped by the commonly used box wrapping machines.

Our present invention also aims to separate and individualize the edgeand finishing treatments of boxes that are first wrapped in our multiplestage treatment box wrapping machine, for which we have a pendingapplication in the U. S. Patent wrapping and box end finishing machineby hand or by any suitable mechanism. We preferably, however, illustrateand use the following described box feeding mechanism for feeding theboxes to the wrapping mechanism and for discharging them from it afterthey are finished.

Referring to the drawings,

The numeral 1 designates a box shaped frame that is provided with a toptable portion and which we preferably term a table frame. This tableframeis provided with a main driving shaft and with cam actuated leverand gear mechanism, and ,also with a box receiving and transfermechanism, all of which will be presently described.

Assuming that the boxes are fed against a stop by any suitable boxfeeding or transferring mechanism or by hand, and that they have beenpartially wrapped in some other machine and left with their blankspartially wrapped. around them, that is, with the blank adhesivelywrapped to their bottoms, sides and ends, and that the top edges of theblank are projecting up above each box.

Then when a box so partially wrapped is fed against the stop arm 2 thefirst movement of the mechanism of our combined turn-in and finishingand box transmitting and discharging mechanism is to move the stop armout of the progressive path of the box.

Then the forward end of the box is engaged by a push block 3 that isclamped on the lower end of a head block B. There are two of these headblocks 13 and C and they have a vertical reciprocal movement ofsufficient stroke to raise above and to drop down behind the box, thehead block B first pushing it forward against an abutment block 41secured to the lower end of the opposite head block C, where it isgripped tightly between the members 3 and 4 of the blocks. The box isthen first pressed down and is firmly seated against the top of thetable portion of the frame by a downward vertical movement of the platesof the end turn in mechanism, which will be presently described.

The turning in of the ends of the blank into the ends of the boxes isaccomplished by two different and independent operations of the end turnin mechanism and the side turn in mechanisms operate in between the twoactions of the end mechanism, and we will first describe the firstaction of the end turn in mechanism. We will state, however, that at thetime the box is being pushed forward against the abutment block 4 thefirst step treatment of turning in the ends of the blocks is performedautomatically as follows:

The box end blank turning in mechanism comprises two verticallypositioned head blocks B and C which are arranged to face each other.

The end turn in mechanism C is fixed relative to the frame of themachine, while the end turn in mechanism 13 has a short reciprocalhorizontal movement by which it engages and moves the box against theabutment block 4. of the turn in mechanism C. After the box has beenmoved by the movable head block against the fixed head block, it isgripped and held rigidly until the edges of the projecting verticaledges of the blank are completely wrapped in the box. The two headblocks 13 and C are supported by and depend from an overhead arm 5 whichis positioned above the table over its center and extends longitudinallyalong its entire length from adjacent to its first stage mechanism. Thisarm has a short vertical reciprocal movement that is imparted to it by across head 6 that is raised and lowered by a cam 7. This cross headcomprises two cylindrical hub members 8 which are connected by a barhaving a central opening 9. Vithin the hubs are secured the lower endsof two tubular vertical hollow standards 10,.the upper ends of which aresecured in hub portions of the overhead arm 5 by pins 11 which passthrough the said hubs and through the standards. The opening in the barof the cross head receives a worm gear 12 through which the threadedupper end of a circular bar 13 passes, the lower end of which is securedto a cam fork 14 having a roller 15 which enters a groove in the camdisk 7, and in this manner the cross head and the overhead arm areraised and lowered for a purpose to be l'lereinafter explained. Upon thehub portions of the cross head are bearings 16 in which is mounted ahorizontal shaft 17 having a worm pinion 18 which meshes with the wormgear 12 carried by the cross head. The outer end of this shaft 17carries a hand wheel 19, by turning which the worm pinion 18 is causedto turn the worm gear 12 in the cross head 6 whereby the threaded rod 13may be lengthened or shortened to suit the depth of various sized boxes.

The overhead arm is provided with a fixed slideway bar 20 that issecured to its bottom in position to receive the head block 0, and witha slideway bar 21 that has a short reciprocal movement, it beingslidably mounted on bolts 22, which extend through the arm. The headblock C is adjustably mounted on the slide bar 20 and it is securedthereon by a set screw 23 in a position to receive each different sizebox that the machine will wrap.

The head block B is also adjustably mounted on the movable slideway 21and is secured thereon in adjusted positions by a set screw 24. Bothhead blocks are provided with guideways 25 that straddle their slidewaybars, and are secured over the side edges of the slideways by cap strips26 that are secured to their opposite sides. As illustrated these headblocks are positioned on their respective. slideways in positions toreceive between them the largest size box the machine will wrap. Thereciprocating slideway bar 21 is provided with a number of gear teeth 27which are engaged by apinion 28 that is mounted on a stud screw 29 thatis threaded into the side'of the overhead arm 5. This pinion 28 alsomeshes with the teeth 30 of one end of a rack bar 31 that is mounted ina slideway that is formed in the overhead arm 5. The opposite end ofthis rack bar is also provided with gear teeth that mesh with a gear 32that ismounted on the end of a short shaft 33 that is suitably journaledin a vertical bearing 34, on the overhead arm. The upper end of theshaft is also provided with a gear 35 that meshes with the teeth of oneend of a rack bar 36 that is slidably mounted in a suitable bearing 37secured upon the overhead arm. The opposite end of this rack bar is alsoprovided with teeth that mesh with a gear 38 which is preferably brazedupon the top end of a square tubular shaft 39 that surrounds loosely asolid square shaft 40. The upper end of this square solid shaft isrounded and passes loosely through the gear 38, the solid shaft having ashoulder at the junction of its round and square portions, which bearsagainst the gear 38. This square tubular shaft extends down through theframe and passes loosely through a gear 41 that is rotatably mounted ina suitable bearing 42 on the frame in which the gear is supportedagainst vertical movement. A rack bar 43 is reciprocally mounted in theframe and its gear teeth mesh with the gear 41. The opposite end of thisrack bar is pivotally connected to one end of a link 44, the oppositeend of which is connected to one arm 45 of a double armed lever, whichis pivotally mounted in a journal block 46, that is secured to the bedplate of the frame. The upper end of the other arm 47 of this doublearmed lever is provided with a roller which engages a groove in one sideof a cam 48 that is mounted on the cross shaft 49. This cross shaft hassecured upon it a bevel gear 50, which meshes with and is driven by abevel gear 51 that is mounted on the end of the main driving shaft 52.The lower end of the solid shaft 40 passes loosely through with one endof a lever 57., which is loosely mounted on a stationary shaft 58. Thein termediate portion of this lever carries a roller, which enters agroove in the opposite side of the cam 48.

The upper end of the solid square shaft 40 carries a gear wheel 59, thefunction of which will be hereinafter set forth. The rack bar 55 has abend, as shown, so as to pass the circumferential edge of a cam 60. Acam 48 is secured upon the opposite end of the shaft 49, which operatesa duplicate arrangement of the levers and rack bars just described,which rack bars operate a duplicate arrangement of the gears 41 and 53and shafts 39 and 40. The upper ends of the right hand hollow shaft 39carry a gear wheel 61, and the upper end of the right hand solid shaft4O carries a gear wheel 62, the function of which will be hereinafterdescribed.

Each head block is provided on its right hand side with a worm pinion 63which is rotatably mounted in bearings formed on the side of each block.Each worm pinion of each head block meshes with a toothed segment 64,that is secured on one end of a pin 65, which is pivotally secured inthe head block. A depending lever 66 is rigidly secured uponthe pin, thelower end of which is arranged to engage a pin 67, which extends looselythrough a long slot 68 formed in each block, and also through a slot 69that is formed through a plate 70 that is reciprocally mounted in aslideway 71 that is formed in the outside edge of the head block, saidpin being threaded into a finger blade or bar 72 which is seated in aslot formed in the outside surface of the plate 70. This finger blade ispivotally secured at its upper end by a pin 73 to the plate 70. The pin67 is provided with a screw driver head to permit it to be adjusted toreceive the stroke of the lever 66 due to the reverse rotary movement ofthe worm by its toothed segment, as will be hereinafter explained.

The worms are each provided with a square axial aperture in which asquare shaft 74 fits loosely, and the head blocks and their worms arearranged in alinement on the overhead arm and the square shaft 74extends across and through and beyond both worms. Consequently the wormsof both head blocks are rotated in unison, and the levers 66 engage bothpins 67 at the same time and swing the lower ends of the finger bladesout from the plates at the same time. The finger blades are returnedinto their slots on the backward stroke of the levers 66 by expansivesprings which are mounted on pins 76 that extend loosely throughapertures formed through the finger blades and are threaded into theplate 70.

The shaft 74 and the worms are rotated by a train of gearing in thefollowing manner:

The pinion 59 on the upper end of the left hand solid shaft 40 mesheswith one end of a rack bar 77, the opposite end of which meshes with apinion 78 that is secured on the end of a shaft 79, the opposite end ofwhich is provided with a bevel gear 80 that meshes with a bevel gear 81on the adjacent end of the shaft 74. Thus the cam 48 through the leverarms 45 and 47 and left hand rack bar 43, imparts movement to the lefthand solid shaft through its pinion 53,

and the gear 59 on the upper end of this shaft operates the rack bar 77which opcrates the gear, the lower. end of whose shaft carries the gear78- which operates the bevel gear 81 on the shaft 74, whereby the worms63 are turned in unison, and the arms 66 thereby moved against the pins67 to swing the plates 72 outward.

The plate 7 0 of each head block has a vertical reciprocal movementimparted to it, of I about a half-inch stroke, which 'movement iseffected in the following manner: link 82 is pivotally secured at oneend to each plate 70 by a pin 83 that extends loosely through anaperture in the finger blade and is threaded into the plate, and the o)posite end of this link is pivotally connectec at one end to a lever84, the opposite end of'which fits loosely on a square shaft 85, that ismounted in sleeve bearings rotatably journaled in bearings 86 that areformed on the head block.

The square shaft is rounded at its rear end and extends through abearing 87 on the transverse portion of the overhead arm 5, and a bevelgear 88 is secured to this end and the shaft is partially rotated oroscillated by a train of gearing in the following manner: The pinion 62on the upper end of the right hand solid shaft 40 meshes with one end ofa rack bar 89, the opposite end of which meshes with a pinion 90 that issecured on the end of a shaft 91, the opposite end of which is providedwith a bevel gear 92 that meshes with the bevel gear 88 on the ad jacentend of the shaft 85. Thus the movement of the right hand cam 48 isimparted to the shaft 40' in the same manner described in connectionwith the left hand cam 48, and the shaft 40, the mechanisms operatingthese two shafts being duplicates of each other, and located on oppositesides of the machine.

After the head blocks B and C have dropped down at a short distancebehind the box, the head block B is moved forward by the pinion 28 andrack bar 31 and as its push assists finger. Then the box is engaged bythe push block 3 and is moved forward against the abutment block 4 ofthe head block C and as the box moves toward that abutment block therear end of the box and the upstanding edge of the blank are pushedagainst the beveled bottom surface of a block 94 carried by the plate 72of the head block G, and as the rear end of the box advances under thisblock 94 the upstanding edge of the blank is bent into the box down tothe edge of the box, which is engaged by the base edges of both blocks93 and 94 when the box is finally gripped between the push blocks ofboth heads. The blocks 93 and 94 are then both raised upward verticallyabout a half of an inch by the movement of their links 82 and lever 84and the square rod 85 and by the same means are then moved straight downuntil the heels of these blocks rest directly on top of the end edges ofthe box, when pressure enough is applied to them through the links tofirmly seat the box against the top of the table, and both finger blocksare then raised and remain up while the side turn in mechanisms advanceand turn over and in and against the inside surfaces of the box theupwardly projecting side edges of the blank.

These mechanisms that turn in the opposite side edges of the blank intothe box are constructed, arranged and operate as folexactly alike adescription of one will sufice for both.

Each head block consists of a base portion 96 that is slidably mountedto be moved in a horizontal plane in a transverse slideway 97 formed inthe table, and a vertically movable chuck block 98 that is verticallyadjustable upon upwardly projecting standards 99 that are formed on thebase 96. The standards are yoke shaped and are provided with guidewaysand each chuck block is provided with a capped lug portion 100 that isslidably mounted in the guideway of the standard. A threaded rod 101 isrotatably mount ed at its upper end in a bushing 102 at the top of thestandard and threads down through the lug 100 of the chuck block, itslower end resting in a bearing 103 in the adjacent end of the base 96.Thethreaded rod is adapted to receive a wrench to turn it to raise orlower the chuck block which has a vertical movement on the standardsullicient to allow it to be adjusted to all heights or depths of boxesthe machine will wrap. This chuck block extends down through a slot inthe table, when adjusted for boxes of slight depth, and it is adjustablymovable up and down to accommodate boxes of different depths, and isfixed in adjusted positions by its cap 104 which can be clamped tightlyto the standards. The chucks face the opposite sides of the box that isto be wrapped and the opposing side members of each chuck are eachprovided with a semi-circular slideway 105, and in each pair ofslideways is mounted a segmental block 106, which therefore travels in asemi-circular path and is moved in this path by a combination of linkand lever members, which are constructed and act as follows:

The segment block is of the form shown in Figs. 2 and 3, and is providedwith a depending lug 107, to which one end of a link 108 is pivoted. Thelower end of this link is provided with an oblong slot and is pivotallyconnected through this slot by a pin 109 tothe upper end of a verticallyreciprocable bar 110, which is slidably mounted in a guide 111 that isformed on a depending portion of the head block.

The lower portion of each of the bars 110 is provided with an adjustablecollar 112 that rests on a spring 113 that is housed to a socket 114that is attached to a cross bar 115, which cross bar is given a verticalreciprocating movement by a forked lever 116, to which it is bolted, andwhich is operated by a cam 117, which is secured upon the main drivingshaft 52. The upper endof the forked lever moves in a guideway of astandard 118, which is bolted to the bed plate. The upper portions ofthe bars 110 are square, but the lower portions thereof are rounded andextend through the springs 113 and sockets 114 to allow for verticaladjustments to correspond with adiustments of the head blocks to fitboxes of different heights. I Each bar 110 has a rib portion 119 thathas a cam curve 120 at its upper end, that engages a roller 121 that ismounted on the depending member 122 of a rock arm. This rock armcomprises a long hub that is pivotally mounted on a pin 123 that extendsthrough it and the sides of the chuck, the depending member 122 and twoarms 124 spaced a short listance apart and extending upward, the end ofeach of which terminates in a fork 125 in which lie rollers 126 whichare mounted on opposite sides of a hub portion on one end of a slidingblock 127, which is reciprocally mounted in a slideway formed in the topof the segment block 106. Arms 12.8 project from the opposite ends ofthe hub, the outer ends of which are connected to the lower ends ofsprings 129 that act to normally hold the rollers 121 in contact withthe ribs 119 of the bars 110. The opposite ends of the springs areconnected to pins 130 that are secured to the sides of the chuck. Thissliding block is provided with a cap 131 that is arranged to clamp aside turn in blade 132, as shown by Figs. 2 and 3. The side turn inblades are of a length corresponding to the inside length of the boxesbeing covered.

Along the front face of each chuck we secure a bar 133, against whichthe upper edges of the sides of the boxes bear, when the turn in bladesbend the extended portions of the sides of the blank over against theinner faces of the sides of the box, as shown by the dotted lines inFig. 2.

' These two chuck heads and their bases are arranged to be moved inunison together toward or away from the longitudinal center of themachine in the following manner:

Each head block is formed with an opening in which is secured aninternally threaded bushing 134, in which is screwed a plug 135, havinga square hole, the outer end of the plug having an annular groove 136.Through these plugs passes a square rod 137, the ends of which arerounded and en ter bushings in the sides of the table; A threaded rod138 extends parallel with and adjacent to the square rod 137, and uponthe end portions of the threaded rod are screwed followers 139,comprising hub members having arms, the outer ends of which arebifurcated, and straddle the annularly grooved ends of the plugs 135.Thus by turning the crank handle 140 on the end of the threaded rod 138,the said rod is rotated, nd the head blocks are moved inward or outward,in their slideways;

The object of threading the plugs 135 to the bushings 134 is as follows:When the boxes pass from the first into the second stage position, thehead blocks stand in such positions relatively to each other that theboxes may pass readily between the bars 133 without touching them, butafter they have reached their proper position, it is necessary thattheir sides should be engaged by the said bars 133, and to accomplishthis a slight inward movement is given to each head bloek,.by turningthe square rod by which. the plugs 135 are turned, and as the plugs whenturned by the square rod are held against lateral movement by thefollowers 139, the head blocks are thereby moved in or out according tothe direction of rotation of the plugs. The square rod is turned in thefollowing manner: A cam disk 141 on the main shaft 52 has a cam whichengages a roller on one member 142 of a double crank arm, which issupported in a bracket 143 thatis bolted to the bed ioc plate of themachine. The other arm 14% connects with the lower end of a connectingrod 145, the upper end of which is pivotally attached to a lever 146,which is mounted on the adjacent end of the square shaft. It will thusbe seen that the cam 1 11 imparts movement to the connecting rod 145, bywhich the lever 1 l6 is rocked and the shaft turned.

The chucks having been adjusted with their guide strips in operativerelation to receive a box and blank between them, the segment block andthe sliding block operate to cause the side turn in blade 132 to turn inthe upwardly projecting side edges of the blank into the interior andagainst the inside surfaces of the box in the following manner:

When the bars 110 are raised by the cam 117 the cam curve 120 at theupper end of the bars first engages the rollers 121 of the rock arm,which causes the lower ends of the rock arms to swing out and theirupper end to push the sliding blocks 127 forward toward the box, whichcauses the side turn in blades to move horizontally forward and engagethe projecting edges of the blank, and in moving forward they barelyclear the top side edges of the box; then as they reach the 'end oftheir inward stroke the pins 109 at the tops of the bars 110 have bythis time moved up with the bars to the upper end of the slots in thelinks 108,

which connect the bars with the segment blocks 106 and thus lift thesegment blocks, causing them to move in an arc of a quarter of a circlein the semi-circular curved slideways of the chucks, which causes thesliding blocks and the turn in blades to tilt upward into verticalpositions, and as the blades tilt over the side edges of the box theybend the edges of the blank over into the box and against its insidesurfaces and the blades press the blank tightly against the insidesurfaces of the box when it swings into a full and a trifle more than afull vertical posi tion. which brings a decided side pressure "of theblades 132 against the inside of the box, thus firmly pressing the edgeof the blank against the inside surface of the box, the turning inblades thus rolling over the edge of the box and pressing flat againstits inside surface, the sides of the box with the turned in blank beingpressed between the said blades and the bars 133.

When the segment blocks move upward in their curved slideways 105 in thechucks,

they lift the rollers 126 of the sliding block 127 out of the yoke ends125 of the arm and swing them up into such a vertical position as isnecessary to cause the finger blade to press the edge of the blankagainst the inside surface of the box.

,lVhen the side turn in blades 132 have been moved against the inside ofthe box meters with the full pressure of their links 108,

pins 67, by which the plates 72 with their end turn in blocks 93 and 94are swung outward or toward each other, and instantly thereafter the rod85 is partially rotated, in the manner previously described, and themembers with the plates 72 are depressed through the medium of the links82, and levers 84, and the blocks 93 and 91 pass down into the box, theends of which pass between the said blocks, and the abutment blocks 3and 4 respectively, whereby the ends of the blanks are folded downagainst the inside surfaces of the ends of the box.

Consequently the end turn in blocks on this their second downwardmovement complete the end turning in operation of the edges of theblank.

These end turn in blocks are so formed that they fit down into the boxbetween the side turn in blades and press the corners of the blanks downsmoothly into the corners of the box. The end blocks then first move upout of the box and then the side blades are swun to a horizontalposition by the downwarr movement of the bars 110, and the links 108,and the rollers 126 of the sliding block 127 are swung down into theforks of the rock arm, and when the curved cams of the bars pass belowthe said rollers 121, the contraction springs 129 swing the rock armsbackward, which movement draws the sliding block and the side turn inblades back out of the path of the box, which is now wrapped as far asthe action of the turn in mechanism of this machine will wrap it, and itis now ready to be transferred to the end finishing mechanism. A stoppin 147 extends through the rear end of the plate 127, and into a recess148 in the rear end of the segmental block, and prevents dropping of theplate in its slideway in the block, when the block has been moved to theposition shown in dotted lines, Fig. 2, in which the plate 127 standsvertical. The blades 132 however are not withdrawn from contact with theedges of the sides of the box, until after the box has been engaged bygrippers 1 19, as will be explained.

The ends and sides of the top edges of the blank have now beencompletely wrapped and glued against the interior surfaces of the box,and are completed, and the head blocks have been raised up above the boxby the upward vertical movement of the overhead arm 5, Then the boxgripping and transferring arms 149 and their operating mechanism act bybeing moved rapidly from the third treatment station back to the secondtreatment station, where the grippers grip the now almost completed boxand transfer it to the third or finishing station, in a manner and bymechanism to be hereinafter described.

The finishing treatment of the now wrapped box consists of administeringa finishing pinching pressure against the opposite ends and in the endcorners of the box, and the mechanism which accomplishes this isadjustably mounted on the overhead arm 5 which has a vertical reciprocalmovement that is timed to act to move the box end clamping mechanismdown behind the front end of the box after it has been moved into thefinishing station by the box transmis sion mechanism, which downwardstroke of the overhead arm is the same stroke that moves the head blocksof the second or turn in station down behind the ends of the box. Thebox treatment mechanisms of both these mechanisms are timed to act inunison, as relates to the reciprocal movement of the overhead arm.

The mechanism that applies the clamping pressure to the ends of the boxin the finishing station comprises two head blocks E and F, each ofwhich is slidablv mounted on a slidewav portion 150 formed on the underside of the overhead arm. each head block being provided with guideways151 that are provided with caps 152. These two head blocks areadjustably mounted at box receiving distances apart on opposite sides ofthe vertical center of the station to fit boxes of different lengths, bya right and left handed threaded rod 153 which extends through athreaded aperture in each head block. At the center of the length ofthis threaded rod it is supported by a split journal box 15-1, which isprovided with a clamping sleeve through which the rod rotatably passes,and a thumb nutv 155 is arranged to close the sleeve to grip the screw,a collar being pinned to the rod on each side of the sleeve to preventendwise movement of the rod. -This screw is also supported at its rearend by a lug 156 which is secured to the adjacent end of the arm 5 andthe end of the screw is arranged to receive a crank lever 1.37, by whichthe operatm may turn it to move the head blocks in positions to fitboxes of different lengths. Each of these head blocks has a hollowchamber opening up into it from its lower edge, and the box edgeclamping mechanism is posi tioned in and depends from this openedchambered end. The mechanism for each head block is of the constructionand arrangement following. and it consists of an eccentric 158 formed ona shaft 159, which extends transversely across the block and is mountedin bearings formed in its opposite sides. The shaft 159 is rotated by abevel gear 160 that is secured on one end of it, and which meshes with abevel gear 161. having a hub which is mounted in a bearing on one sideof the head block, the gear 161 having a square aperture through whichpasses a square shaft 162. This square shaft extends past. both heads,and it is, provided at its inner end with a bevel gear 163 that mesheswith a bevel gear 161 that is secured on the lower end of a verticalshaft 165 that extends up through bearings 166 formed on a bracket 167secured to the overhead arm 5. A spur gear 168 is secured on the upperend of the shaft 165, which meshes with the gear 61 that is mounted onthe upper end. of the right hand square tubular shaft 39, which extendsdown through one of the large tubular standards 10, the lower end ofwhich carries the gear 41 which meshes with one of the straight rackbars 43, as previously described.

Two arms 169 are rotatably mounted on the eccentric of the shaft andtheir ends are pivotally secured to lugs 170 that are formed on a plate171 that is provided with guideways and is slidably mounted in slidewaysformed in the opposite sides of the head block. An abutment bar 172which prefer-- ably consists of a piece of wood, is clamped to the'outerend of the plate by a clamping cap 173. The abuti'nent bar is arrangedto fit snugly down inside of each box between its sides at its ends, andit has a short reciprocal movement against the. inside surface of theadjacent end of the box due to the throw of the eccentric. which acts topress the bar against the inside surfaces of the wrapped ends of theblank that were glued. to the box at the second station. but which. needa pinching pressure to smoothly flatten them against the inside ends andcorners of the box.

Upon the eccentric shaft at the side of the arms two short levers 174are mounted,

the free ends of which are pivotally secured to the opposite sides ofone end of a link 175. The opposite end of this link is secured to oneof the ends of two pairs of links 176 and 177. ()ne end of the links 176is pivotally secured to a block 178 which is secured to a. cross bar179. which is bolted to the sides of the head block. The opposite endsof the other two links 177 are pivotally secured to lugs which areformed on a plate 180, that is bolted to a pressure bar 18L the frontend of which is covered with a strip of felt. The pressure bar 181 andthe felt strip aremade wide enough to extend across the outside end ofthe greatest width boxes covered by the nia-' chine. This pressure barhas guidewav Side edges which fit in slideways 182 formed in the insidesof the side pieces of the pressure plate 171. The toggle links 176 and177 due to the partial rotative throw movement of the eccentric shaftimpart a short reciprocal movement to the outside pressure bar 181,which is arranged and timed to move against the outside surface of theend of the box, and to oppose the pressure movement of the insideabutment bar 172 against the inside of the box. Both movements takeplace at the same time and pinch or clamp the ends,

of the box between them. The'block 172 acts as an abutment for thetoggle power pressure of the arms 177. When a box arrives at its properstopping position of the finishing treatment station, the overhead armis at the top of its upward stroke and consequently the head blocks areraised above the path of the incoming box. Both head blocks arepositioned and timed so that when a box is transferred from the turn-instation to the finishing station the presser bars will stand directlyover the ends of the box, and these presser bars are spaced as far apartas the eccentric shaft will throw them, which would be preferably abouta. quarter of an inch.

Then when the overhead arm moves down, these bars straddle the oppositeends of the boxes at their upper edge portion. Then the cam and gearingmechanism that operates the eccentric shaft of the head blocks shaft.

acts to cause the eccentric through the arms 169 to move the blocks 172against the inside surface of the ends of the box, and through thetoggles 176 and 177, link 175 and levers 174, to move the presser bar181 against the outside surface of the box, and thus very tightlypinches the end edges and corners of the box between them.

The box has now been completely Wrapped and its corners finished and itis ready to be released and discharged from the ma chlne.

The presser bars then move apart to release the box by the action of theeccentric The overhead arm then raises the head blocks above the box,and it is engaged by a push arm 182 and is moved off from the dischargeend of the wrapping machine.

The mechanism that engages the box and discharges it from the finishingstation and from the machine is a part of the same mechanism that movesthe box from the turn in to the finishing station, and this boxtransferring and discharging mechanism will now. be described.

The stop member 2 comprises an arm that is pivotally mounted on a pin188 which passes through to a support or carriage 18% which is mountedon a slideway 185 that extends longitudinally of the length of themachine to its discharge end, commencing adjacent to the turn inmechanism and extending under the finishing mechanism but manners belowthe level of the top of the table to which itis secured at its ends andat intermediate points. This slideway 185 is provided along its oppositesides with pro]ect ing slide rails 186 and the carriage is arranged tostraddle the under side of the slideway 185 and fit slidably on and overthe rails 186, the said rails being of a length to permit the carriageto be adjusted to bring the stop arm 2 in position to engage boxes ofdifferent lengths.

The carriage 184 as illustrated is positioned below the side and turn inmechanism, the stop arm 2 being in a position to stop the largest sizeboxes the machine will wrap.

The side and end turn in mechanisms are also set to receive the largestsize boxes the machine will wrap. In order to move the carriage 18-1 andits stop arm to stop smaller sized boxes down to the smallest size themachine will wrap, we provide a hand operating threaded rod 187 which isrotatably threaded to the carriage, while its outer end is rotativelymounted in a bearing 188 formed on the cross rib 189 of the adjacent endof the table. A hand grasping knob 190 is mounted on. the outer end ofthe rod, which is so arranged in its-bearing that when it is turned byhand the bracket and arm are moved along the rails 186 of the slideway185, to the required point relatively to the length of boxes beingcovered.

The longitudinal center of the turn in station of the machine is definedby a vertical arrow (Fig. 1) and all. adjustments of the box wrappingand transferring mechanisms for different sizes of boxes at this turn instation are made relative to this point as the center of the length ofthe box being wrapped at this station or mechanism.

A slot 191 of suitable length is formed in the bottom of the slideway185. A spur gear 192 is loosely mounted on a cross shaft 193 thatextends across and is secured in hearings in the sides of the table. Thespur gear projects up into the slot 191 and meshes with a toothed rackbar 194 which we term the box shifter rack, and which is mounted in theslideway 185. The gear wheel 192 has a pinion gear 195 rigidly securedthereto in any suitable manner, and this pinion meshes with a toothedbar 196, the lower end of which is bolted to a forked lever 197, whichstraddles the main shaft 52, and is provided with a roller which entersa suitable cam groove in. the cam disk 60, which is mounted on the mainshaft. The upper end of the toothed bar 196 passes through a guideway198, which is rigidly secured to the shaft 193. This box shifting rackbar is provided with a centrally projecting flange 199 which extendsthroughout its full length. This box shifting rack is held in theslideway by caps 200 which are screwed to the top edges of the slideway.To the flange which project above the flange and form bearings for theopposite ends of a right and left hand threaded rod 202. Upon theopposite ends of the threaded rod 202, blocks 203 are threaded, theupper ends of which are bifurcated to receive the lower ends of thegripping arms 149, which are rigidly mounted upon pins 204, which arepivotally mounted in the bifurcated ends of the said blocks, their endsextending beyond the sides of the blocks. Upon one end of each of thepins 201, is rigidly mounted an arm 205, the arms extending in oppositedirections, and upon the outer end of each arm is mounted a roller 206.Upon the opposite end of each pin is secured a nut or washer 207, and acoil spring 208 is mounted on the pin between the nut and the block 203,one end of which enters a hole in the block, these springs-being undertension which is exerted to raise the arms so that their outer ends,which are upturned, will extend a slight distance above the plane of thetable. The lower ends of the blocks 203 are also bifurcated, and areslidably mounted on the flange 199 of the rack bar 194.

' The box gripping arms 1 19 have their upper ends arranged to standvertically upright when at the limit of their upward movement, and theseupper ends are adapted to move against and grip the opposite ends ofeach box at the turn in station, with sufiicient pressure to hold it andmove it to the finishing station, as will be hereinafter described. I

The outer end of the threaded rod 202 is provided with a transverselypositioned pin which with the terminal end of the rod is adapted toreceive a hand operated socket wrench by means of which the threaded rodmay be turned and the blocks 2023 moved toward or away from each otherto grip any size box from the smallest to the largest; as illustratedthey are shown arranged to grip the largest size box the machine willwrap. These box grippers are moved down out of the way of each box afterthey deliver it to the finishing station, by a longitudinal bar 209, theupper edge of which terminates in a horizontal lip 210, which at alltimes engages the rollers 206 on the arms pivotally attached to levers211 and 212 respectively, the opposite end of the lever 212 beingloosely mounted on the threaded rod 138, which extends transverselyacross the table and is mounted in bearings in opposite sides of theframe. One end of this rod is provided with a crank handle 140. by whichthe rod may be turned to effect the ad ustment of the side turn inmechanisms, as previously described. The lever 211 is mounted midway ofits length upon a statlonary shaft 205. The opposite ends of the bar209, are

213 which extends transversely across the table and is supported in thesides thereof. The opposite end of this lever 211 is piv otally attachedto one end of a connecting rod 214, the opposite end of which ispivotally connected to a lever 215 which is mounted midway of its lengthupon the stationary shaft 58, also supported in the side frames of themachine. The opposite end of the lever 215 carries a roller 217 which isengaged by a cam 218 on the circumferential edge of a disk 219, which isrigidly mounted on the shaft 49, which is supported in bearings in theside frames of the machine. The roller is held against the edge of thecam disk 219 by a coil spring 220 which surrounds the shaft 58, and isattached at one end to the lever 215 and at the other end to a collar onthe said shaft. The shaft 19 carries a bevel gear wheel 50, which mesheswith a similar gear 51 on the adja-' cent end of the main shaft 52. 1

As the disk 219 rotates, the cam 218 engages the roller 217, therebyrocking the lever 215, by which the rod 214 is drawn upon and the lever211 rocked, its upper end being raised together with the upper end ofthe lever 212, which the lever 211, through its connection with the bar209. This movement of the levers 211 and 212 raises the said bar 209,the lip 210 of which engages the rollers 206 and the arms 205, which,with the grippers, are permitted to rise to the position shown in Fig.1, the cam 218 being timed to effect the raising of the bar 209, toallow the grippers 1 19 to engage each box after the turn-in treatmenthas been accomplished, and to advance the box to its finishingtreatment. The rear end of the rack bar 194: has secured thereto anupright 221, which is similar to the blocks 203, and this uprightsupports the box discharging. arm 182, rigidly mounted on a pin whichpasses through the upright and carries at one end an arm 222, similar tothe arms 205, and which is also provided with a roller similar to therollers 206 on the arms 205 The arm 182 is also actuated in onedirection by a spring similar in all respects to the springs 208, whichraise the arms 205. The roller carried by the arm 222 is in continuousengagement with the lip of the bar 209, and the discharging arm 182 is,therefore, actuated simultaneously with the gripper arms 14.9 todischarge the finished box from the machine.

It will thus be seen that at each rearward movement of the rack bar abox is transferred from the turn-in position to the finishing positionby the grippers 149 and the box which was in the finishing position iscaught by the arm 182 and discharged from the machine.

At the time the box is engaged by the front end turn in mechanism andits formoves 1n unison with teeth of this rack ward movement of about aninch against the rear abutment block 4 has commenced,

the stop arm 2 is swung down away from the box by its operatingmechanism which is constructed and arranged as follows:

he carriage 184 is provided with a depending portion, in which avertically arranged rack bar 223 is mounted. The gear bar engage apinion 224 that is mounted on the supporting pin 183 of the stop arm.The lower end of this rack bar is provided with a shoulder 225 which isadapted to be engaged by a longitudinal lip 226 on a horizontallypositioned bar 227 which is secured to the upper end of a bar 228, thelower end of which is secured to a reciprocating cam fork 229, the lowerend of which straddles the main driving shaft 52, and is provided with aroller which engages the cam 141 that is secured on the main drivingshaft. The cam 141 is timed to draw the bar 228 and consequently the bar227 down, at the instant the rack bar moves forward to bring thegrippers 149 to the turn-in position, and as the lip of the bar 227engages the shoulder 225 on the rack bar 223 and depresses the said rackbar, its engagement with the gear wheel 224 causes the same to turn theshaft 183 upon which the stop arm 2 is rigidly mounted, and the saidstop arm is turned down to the position shown in full lines in Fig. 1.The upper end of the rack bar 223 terminates in a horizontal arm 230which is engaged by a longitudinal flange of the rack bar 194, as thesaid rack bar moves forward and the stop arm is thus held down until itis released by the rack bar on its rearward movement. The stop arm 2 isthrown up by a coil spring 231 which surrounds a projecting end of thepin or shaft 183, upon which the stop arm is rigidly mounted. One end ofthis spring enters a hole in the adjacent side of the carriage, whilethe other end thereof enters a hole in a collar 232 which is securedupon the adjacent end of the pin 183, the tension of the spring causingthe stop arm to swing to a vertical position, when it is in position tostop a box. After drawing the rack bar down, as previouslydescribed, thecam 141 raises the bar 227 to the limit of its upward movement, as shownin Fig. 16, when its lip 226 is ready to again engage the shoulder 225on the lower end of the rack bar 223, when the same is released by therack bar 194 and thrown upward by the spring actuated gear wheel 224.

The box is now in its turn-in treatment position and it is engaged andoperated on as above described.
